In the near future, a police officer specializes in malfunctioning robots. When a robot turns out to have been programmed to kill, he begins to uncover a homicidal plot to create killer robots... and his son becomes a target.
I saw this one on video in the early 90s only because Gene Simmons was in it. I really like it. It's not a fantastic movie, but like Selleck put it, it's a good popcorn film.
